Abstract

Refrigerant is circulated in a predetermined flow direction comprised of a heat-rejecting heat exchanger (4), intermediate throttle valve (6), receiver (8), evaporator throttle valves (10), evaporator (14), compressor (20) and flash gas tapping line (26). The flash gas tapping line is connected to the receiver and to the compressor. An independent claim is also included for a refrigeration circuit operating method.
